Thanks. I played around yesterday and found out the way.

There is a problem with font<- .
g<-gtext(con=T)
enter some text, and select a chunk of text.
font(g) <- c("color"="red")
Now I would like to change the color back into "black". But font(g) <-
c("color"="black") does not work.
Thanks

Thanks, John,
Here is some code to show what I want to do. BTW, it seems there is a
bug in svalue in gWidgetstcltk for gtext when using the drop=T
argument.
getsel <- function(obj, toolkit, ...) {
### get the selected text from gtext
getWidget <- gWidgetstcltk:::getWidget
if(tclvalue(tktag.ranges

want to click a
button after making the selection to capture the text? or some other way to
indicate that you have made the selection?

gWidgets is quite good. However, I want to get the selection text chunk as
well as the index, but the index arguments does not work for gtext.

[1] "cde"

You can find examples of using tcltk here:
http://www.sciviews.org/_rgui/tcltk/
Also the gwidgets package is a toolkit independent
layer that can run on top of tcltk or RGtk and it is described
with many examples here:

What I want to do is:
1, creat a text box, insert text into that box.
2, select chunk of of the text by mouse, and link it to a lable. so I would
like a way to get that chunk of text.
Can I do such job with tcltk? Any relavant tutorial materials?
Thanks
